TY - JOUR A2 - Pan, Jing-Hu AU - Mouronte-López, Mary Luz PY - 2021 DA - 2011/08/14 TI -公共交通网络建模:SP - 3280777 VL - 2021 AB -公共交通网络(PTN)为城市提供流动性和获得社区资源、就业、医疗保健、基础设施和其他资源。本研究研究了不同现实世界ptn中节点间链接的形成过程。我们发现，以局部、全局和拟局部相似性指标作为解释变量的广义线性模型(GLM)可以很好地解释这一过程。在建模过程中，采用二项概率密度函数描述响应变量，并用logit函数作为连接函数。在交叉验证过程中，使用下采样方法，平均精度和接受者工作特征曲线(AUC)指标下的面积都高于0.99。大部分PTNs的kappa值均大于0.93。在最后的验证阶段，召回和特异性度量值为1。大多数PTNs的准确度和精密度参数分别大于0.99和0.87。为了达到更好的效果，只有一个ptn需要使用平滑的自举方法。 The similarity measures with the greatest influence on the model were determined. We also assessed the impact of link removal on the global efficiency of PTNs, considering several similarity indexes. Additionally, we find that most of the networks show low local and global efficiencies (≤0.20), as well as travel times with a relevant variability, exhibiting standard deviations larger than 790 seconds. Significant similarities exist between the cumulative probability distributions of the local efficiency in all PTNs. With respect to the centrality measures, the eigenvector centrality presented a strong correlation with the hub/authority centralities (>0.80), while the pagerank showed a moderate, high, or very high correlation with the degree in all PTNs, >0.50.
